林草植被恢复建造是水土保持型生态农业建设中的重要一环,也是安塞试区极具特色的一个重要方面.进入“九五”以来,试区在整体推进水土保持型生态农业建设中,进一步加强植被建造,调整土地利用结构,生态经济良性循环态势已经呈现出来.1999年农林草地面积比例为 1:2.0:2.2。“九五”前4年平均耕地面积约为“七五”之初的1/2,然而粮食平均单产却是“七五”的 2.85倍,达到 2280kg/hm~2,总产依然得到增加.盖度0.6以上的植被的覆盖率达到57%,天然灌木林成片出现.年输沙模数较治理之初减少80%以上. The re-vegetation is an important part of conservational eco-agriculture construction as well as an aspect with distinctive features in Ansai experimental region, (i. e. Zhifanggou small watershed). The watershed has further stressed the re-vegetation and adjusted the land use ratio of farmland, woodland and grassland, in the process of advancing the whole conservational ecoagriculture construction in the period of 1996-2000, so that the fine state of ecological economy system cycle has emerged. The area ra... |
